I had 3 episodes of what felt like breath being taken away in my chest and then thought I was going to pass out. It lasted about 10 seconds and all went away. These 3 episodes happened in a 7 week period. On a couple other occasions I felt my heart race and pound for about 6 beats. The dr had me wear a heart monitor for 30 days. I felt like nothing happened while I wore it but the dr told me they caught 3 different episodes of my heart racing to 110 for 6 beats. I then had a calcium score test. Came back at 0 and also a echocardiogram that showed a healthy heart. My dr wants me to take beta blockers. Is this even necessary? I don’t want to be on them but also don’t want those freaky episodes to keep happening.
